Foamed aluminium board is as one of a kind of the most widely used foamed aluminium material, although it has many excellent performances, but being seldom used alone in practical application, main application mode is to be combined the sandwich component of formation with traditional metal compaction sheet material, and constitutes compound foamed aluminum plate.But, but it is affected by the impact of foamed aluminium porous character, the splicing degree of the metal compaction sheet material of outer layer and the foamed aluminium board core body in intermediate layer is incomplete, splicing face non-refractory and easily aging, it is easily caused the bond strength between metal compaction sheet material and foamed aluminium board core body to reduce, the phenomenon that metal compaction sheet material and foamed aluminium board core body are peeled off each other even occurs.
Owing to compound foamed aluminum plate exists drawbacks described above, those skilled in the art are promoted to propose a kind of brand-new idea, if foamed aluminium board self can be made to have surface compact layer, just can avoid the defect that compound foamed aluminum plate exists completely, for this, those skilled in the art have started the research work of foamed aluminium board top layer densification, although it is also proposed some achievements in research, but, these achievements in research only rest on laboratory stage mostly, it is difficult to apply to industrialized production, market is needed badly again this foamed aluminium board with surface compact layer, and the technical merit of present stage also cannot meet industrial production demand.
Summary of the invention
For prior art Problems existing, the present invention provides a kind of device prepared and have surface compact layer foamed aluminium board, fully meets industrialized production needs, it is possible to continuous and stable production has the foamed aluminium board of surface compact layer, and the thickness of surface compact layer is controlled.
To achieve these goals, the present invention adopts the following technical scheme that a kind of device prepared and have surface compact layer foamed aluminium board, including foaming furnace, transmission band, foam surge chamber, surface compact floor generate room and sheet material cools down forming room, the foam outlet of described foaming furnace connects with transmission band one end, be sequentially arranged above foam surge chamber at transmission band, surface compact floor generates room and sheet material cools down forming room, and the foam outlet of foaming furnace communicates with foam surge chamber；Generate at described foam surge chamber and surface compact floor and sheet material limit thick baffle plate is set between room；Generate indoor location at described surface compact layer and have froth breaking net, by froth breaking net, the foam flowed through within the scope of its interception is crushed, after bubble collapse, form surface compact layer, there is the foamed aluminium board of surface compact layer and undertaken cooling down molding by sheet material cooling forming room.
Described froth breaking net adopts stainless steel cloth, is provided with board-like electromagnetic heater directly over froth breaking net, offsets to indulge in serfing the Net by board-like electromagnetic heater and is heated, and accelerates bubble collapse by heating froth breaking net.
The height of described froth breaking net and tilt adjustable, adjust dense layer thickness by the height or angle of inclination changing froth breaking net.
It is water-cooling pattern or air cooling way that described sheet material cools down the type of cooling of forming room's employing.
Beneficial effects of the present invention:
Present invention firstly provides and form surface compact layer by the mode of the broken foam of froth breaking net, and by the mode of Electromagnetic Heating froth breaking net realize foam acceleration crush, realize surface compact layer rapid solidification by the mode of quickly cooling, thus realizing the preparation with surface compact layer foamed aluminium board simultaneously.The present invention fully meets industrialized production needs, it is possible to continuous and stable production has the foamed aluminium board of surface compact layer, and the thickness of surface compact layer is controlled.
Accompanying drawing explanation
Fig. 1 is that a kind of of the present invention prepares the apparatus structure schematic diagram with surface compact layer foamed aluminium board；
In figure, 1 foaming furnace, 2 transmission bands, 3 foam surge chambers, 4 surface compact floor generate room, and 5 sheet materials cool down forming room, the 6 thick baffle plates of sheet materials limit, 7 froth breaking nets, 8 board-like electromagnetic heaters, 9 foams, 10 surface compact layers.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, a kind of prepare the device with surface compact layer foamed aluminium board, including foaming furnace 1, transmission band 2, foam surge chamber 3, surface compact floor generates room 4 and sheet material cools down forming room 5, the foam outlet of described foaming furnace 1 connects with transmission band 2 one end, be sequentially arranged above foam surge chamber 3 at transmission band 2, surface compact floor generates room 4 and sheet material cools down forming room 5, and the foam outlet of foaming furnace 1 communicates with foam surge chamber 3；Generate at described foam surge chamber 3 and surface compact floor and sheet material limit thick baffle plate 6 is set between room 4；Generate in room 4 at described surface compact floor and froth breaking net 7 is installed, by froth breaking net 7, the foam 9 flowed through within the scope of its interception is crushed, form surface compact layer 10 after foam 9 is broken, there is the foamed aluminium board of surface compact layer 10 and carry out cooling molding by sheet material cooling forming room 5.
